Description
Product Introduction & Engineering Value
The BOR86 A413746 is a system-level Metso Automation control board intended for installed-base support and replacement work. Its exact electrical role, firmware revision, connector layout, and platform compatibility should be verified from the equipment documentation and the module nameplate before installation.
For maintenance teams, the value is straightforward: a correctly matched spare can reduce downtime when an obsolete or unavailable control assembly fails. Do not treat the part number alone as a complete interchangeability reference; revision markings and the host system configuration matter.
Technical Specifications
- Manufacturer: Metso Automation.
- Module designation: BOR86.
- Part number: A413746.
- Assembly type: Industrial printed-circuit-board module.
- Functional classification: Central control module, according to supplier listings.
- Application class: Metso Automation control-system spare.
- Reported country of origin: Finland.
- Firmware: Not established from the publicly available listings; verify the installed revision before deployment.
- Power requirements: Not published in the sources reviewed; confirm voltage, current, and permitted tolerance from the applicable Metso documentation.
- I/O and communications: No verified public specification was found for channel count, network interfaces, or protocol support.
- Mechanical compatibility: Must be checked against the receiving rack, backplane, connector arrangement, and enclosure clearances.
- Replacement status: Treat as a legacy or installed-base support item unless current Metso/Valmet documentation confirms active production.
The available supplier information is limited and does not provide a complete datasheet. A nameplate photograph, cabinet drawing, or host-system model is needed to confirm a true drop-in replacement.

Field Application & Trench Experience
A plausible replacement scenario is a process line where the existing Metso controller began dropping out intermittently after years of service. The maintenance team initially suspected the power supply, but the fault followed the BOR86 board when the control assemblies were swapped. Before installation, the replacement was checked against the original part number, revision marking, connector keying, and cabinet records. The system was then tested in a controlled maintenance window with permissives inhibited and field outputs verified before returning the line to automatic operation.
Potentially relevant applications include:
- Metso Automation controller replacement in a continuous-process control cabinet.
- Central-board substitution during a planned outage on a pulp, paper, or minerals-processing line.
- Troubleshooting intermittent controller resets where the fault must be isolated between power, backplane, processor, and field I/O assemblies.
These are application examples, not confirmation of a specific plant platform. Confirm the host system before procurement.
QA & Testing Transparency
A responsible inspection procedure for this part should include:
- Photograph and record all labels, revision codes, connectors, and visible component markings.
- Inspect the PCB for corrosion, cracked solder joints, damaged edge contacts, contamination, and evidence of overheating.
- Compare the board mechanically with the failed unit, including connector position and mounting features.
- Test the assembly in the correct Metso-compatible chassis or an approved bench setup, if available.
- Verify startup behavior, diagnostics, communication status, and fault reporting.
- Record firmware or configuration data separately; do not assume that a board with the same part number contains the same revision.
Be precise about condition. One supplier describes its A413746 unit as a used assembly removed during plant disassembly and states that it was not retested. That is different from tested refurbished stock, new surplus, and factory-new material.
Veteran’s Tech Trap Guide
⚠️ Do not skip revision matching. A413746 may appear identical externally while differing in firmware, board revision, or host-platform compatibility. Compare every visible code with the failed module.
⚠️ Do not power-test it on a loose bench without the correct interface. A control PCB can require a specific rack, backplane, grounding arrangement, and companion modules. An improvised test setup may produce misleading results or damage the board.
⚠️ Protect the edge connectors. Use ESD controls, avoid touching contacts, and inspect the backplane before installing a replacement. A contaminated or mechanically damaged connector can make a good BOR86 appear defective.
PRO TIP: Preserve the failed board until the replacement has completed startup, diagnostics, communications, and functional testing. It may still contain the only useful evidence of the original failure.
Dynamic FAQ
Is A413746 the same as BOR86?
Public product listings associate A413746 with the BOR86 designation. Confirm the complete label and revision before ordering because a matching designation does not by itself prove system interchangeability.
Is this a PLC I/O module?
The available listings describe it as a central control module or PCB assembly, not as a conventional discrete or analog I/O module. Confirm the host platform and cabinet documentation for the precise function.
Does the part include firmware?
The sources reviewed do not establish the firmware version or configuration state. Ask the supplier for clear photographs of all labels and verify whether the board is supplied as hardware only.
Is this part new surplus?
Do not assume that it is. One listing explicitly describes the assembly as used, removed from a dismantled installation, and not retested. “New surplus” should be supported by unused-condition evidence, original packaging where applicable, and a documented inspection report.
What should be checked before purchase?
Request photographs of the nameplate, BOR86 marking, revision codes, connectors, and any serial or firmware labels. Also provide the receiving system model, rack position, and the failed board’s revision data.
What warranty should I expect?
Warranty terms depend on the seller and the declared condition. The reviewed supplier states that its items are not factory-new and that the original manufacturer’s warranty cannot be enforced through that seller. Obtain the seller’s written warranty, test scope, return period, and failure-handling procedure before issuing a purchase order.
